| Reproduction Preferences Additional Information | Wilson (1970b) stated that the larvae spend between six weeks and two months in the plankton. Reproductive seasonality is unclear but George & Warwick (1985) and Wilson (1970) have both reported larval settlement in March in the Bristol Channel and Plymouth areas respectively. Wilson (1970) found a spawning period from January to March in Plymouth.
Possibly has similar lifespan to Sabellaria alveolata (up to 9 years). Fecundity and recruitment may be variable (Holt et al., 1998) but may be similar to Sabellaria alveolata. |
